b all whom it may concern.'

Be it known that l, ADDISON B. CARLI., a citizen ofthe United States,residing at New York, in the county of New York and State o f New York,have invented a new and useful Barrellfiller, of which the following isa specification.

The present invention relates vto an iinprovement in barrel fillers, andhas for an ol ject to provide an automatic.barrelllerfor cutting off theflow of liquid when thebarrel or container is filled to thedesiredlheight, and wherein the discharge of thefluid into the barrel is had`from the lower end `of a nozzle, which projects into the bung, or topof the barrel.

Another object of the invention is to pro vide a nozzle, which isdetachably mounted on the body of the lillerand which is inter` .lockedor dis-engaged fromthe body by the rotation of the nozzle in either onedirection, or the other. This object of the invention contemplates themounting of a float in one side of the nozzle, and providing aconcentric connection between the laterally offset float and the body,so that the iloat may be free to rise and fall and control the selfclosing valve `in the body, and at the same time the nozzle may bereadily turned in either direction to remove the nozzle or replace thesame.

lt is a further object of the invention to provide a discharge nozzlefor barrel fillers, wherein the fluid is discharged from the lowerl endof the nozzle and wherein an ec" centric float chamber is disposed inone side of the nozzle. and has the oaenino thereof through the adjacentside of the nozzle slightly above the lower end thereof, so that thesuction created by the outflow of fluid into the barrel will not drawthe fluid out of the float chamber to thus prevent the free action ofthe float. The float chamber is provided with a vertically movableVfloat which is suitably spaced from the walls of the float chamber toprevent sticking of the float, and providing for its free action.

Other objects and advantages of this invention will be more clearlybrought out from the following description of the present preferredembodiment of the invention, the same being disclosed in theaccompanying drawings, wherein lligure 1 is a side elevation of theiniprovcd barrel filler.

Referring to these drawings, wherein like parts aredesignated by similarnumerals of reference, designates the body of the filler, which is inthe form of a valve casing having an intermediate horizontal web 16suitably apertured, and provided with an upstanding valve seat about theaperture. A valve 17 is adapted to engage the valve seat and be heldthereto by Va spring 1S, which surrounds theA upstanding valve `stem 19.The valve stem 19 passes lupwardly into a guide 20 formed vwithin a cap21 detachably placed upon the upper end of the body 15, and preferablyengaging screw threaded relation with the body, as shown in Fig. 2. rlhespring 18 bears at one end against the valve 17 and at its opposite endagainst the guide 2O so as to normally urge the valve 17 against thevalve seat. A. suitable inlet nipple 22 leads from the rear side of thebody 15 `above the web 16, and is adapted for connection with a flexiblehose, or the like, through which liquid is conveyed to the filler.

The stem 19 of the valve projects downwardly from the valve 17 throughthe opening in the web 16, and is seated in a stepped bearing or guide23, upstanding from the lower wall of the body 15. The guides 20 and 23hold the valve stem 19 in true vertical alinement, so as to insure thetrue seating of` the valve 17 on the valve seat, and to prevent lateraldisplacement of the valve 17, when operated by the mechanism hereinafterdescribed. The lower end of the valve stem 19 has an outstanding flangeor rim 24 constituting Van abutting shoulder against which the finger 25is adaptedto strike for raising the valve stem 19 and opening the valve17. The finger 25 is fixed upon a transverse shaft 26 extendinghorizontally and' transversely through the body 15 behind the valve stem19. As shown in Fig. 4,

one end of this shaft 26 is journaled in a 'bearing 27 in the form of aboss projecting inwardly from the side of the body 15, and the oppositeend of the shaft 26 is journaled in aninwardly projecting sleeve or boss28 preferably integral with a detachable ycap 29 fitted in the oppositeside of the cas- Y' turned to raise thefinger 25 against the tensionV ofthe spring 18. The outer end of the VVshaft 26 has a rectangular shank30 lying adjacent to the sid@J of the body 15 and adapted to receive theangular socket 31 of an arm 32. As shown to advantage in Fig. 4, the arm32 has a flat inner side adapted to lie close against the side of thebody 15, and as shown in Fig. 1, to move against a flat segmental guideor bearing 33 projecting laterally'from the body l5 and terminating atits rear end in a stop 34. The stop 34 projects laterally and outwardlyfrom the guide 33 and engages the rear side of the arm 32 when thelatter is in its lowermost position, as shownY in Figs. 1 and V4, and inposition to admit the seating of the valve 17 under theV action of thespring 18. A retaining nut 35 is detachably mounted upon the threadedouter extremity of the shaft 26, the nut bearing against the angularsocket 31 of the operating arm to hold the latter on the shank 30 of theshaft.

The lower end of the body 15 is offset forwardly as at 36 and isinternally threaded at its lower end to `receive a tubular nozzle 37,which is detachably mounted upon the body 15 by reason of its threadedengagement therewith. This nozzle 37, as may be best seen from Figs. 2and 5, has an eccentric float chamber 38 mounted in one side thereof andextending substantially throughout the entire length of the nozzle 37,although the length of the oat chamber is immaterial. The float chamberis closed at its lower end by a plug 39 threaded into the lower end ofthe chamber 38, as shown in Figs. 2 and 7, to entirely close the lowerend of the fioat chamber, so that the fluid passing downwardly out ofthe nozzle 37, through the crescent shaped outlet thereof, cannot bysuction disturbthe contents of the float chamber. The outer side of thefloat chamber 38 preferably merges into the adjacent siderof the nozzle37, as shown to advantage in Figs. 6 and 7, and this common side of thefloat chamber and the nozzle is provided with one or more openings 40adjacent the lower end of the nozzle 37 to receive iuid from the barrelwhen the latter is nearly filled, and to admit the Huid to the fioatchamber. Within the chamber 38 is a float 41. As shown in Figs. 2, 3 and6, the float is relatively small in diameter, as compared with the innerdiameter of the chamber 38, so as to provide a space between the oat andthe inner wall of the chamber. The float is held concentric within thechamber 38 by guides or spacers 42, in the form of wings or lugsoutstanding radially from at least three sides of the float, and beingequally spaced thcreabout so as to hold the float centrally in thechamber, as shown in Fig. 6. The float is thus permitted to movefreelyup and down within the chamber 38, without liability of sticking orproducing undue wear or friction on the float and chamber. The float 41is connected by a suitable connecting element 43, such as a wire or rodas shown, with a latch lever 44 pivotcd upon the body 15 to control theoperation of the self-seating valve 17. The rod or connecting element 43extends down into the nozzle 37 and in order to protect the rod 43 fromcontact with the fluid passing down through the body and nozzle, aninclosing tube 45 is employed which projects downwardly from the body 15and opens through the body thereof immediately beneath one end of thelatch lever 44.

In order that the nozzle 37 may be turned either to the right or left,and rotated a considerable number of times, to entirely detach thenozzle from threaded engagement with the body 15, or to bind the nozzletightly in the lower end of the body 15, it is essential to so arrangeor dispose the connection be- A With:this purpose in view, 4the presentinvention provides .an upstanding *socket for nipple 46onthetopofitheiiioat chamber 38,

whichsocket 46 islocated concentric to the nozzle-37. Theconnecting wireorelement 43 is -securedto thesfloat V41 atone side thereof inverticalalinement withithe socket 46, as shown in iFig.12fo;tthedrawings, .and is secured to the lioat preferably byan eye 47, whichpasses `fthrough one Vof the wings or radiating spacers 42 atthetupperend of the float 41. The socket 46 is adaptedlto slid ably and rotatablyreceiveiithe lower end of the protecting tube 45 therein. rlhe tube 45is threaded at its upper end into a threaded socket 48 'openingAdownwardly 4through the upper wall oi the ofset portion 36 of the body.Thus, when the nozzle 37 `is turned-to screw up or unscrew the same, the

ears provide a transverse Ipassage or channel to receive therein theouter-long arm of the latch lever 44. The lever 44 is ulcrumed upon apivot bolt or pin 51 passing transverselyy .through -the outer ends ofthe ears 49 and 50 to dispose the outer-end of the latch yleverimmediately over the socket 48 and tube 45, whichis'litted therein. Thisouter end of the latch lever is hooked or arched downwardly as Vat 52to-receive thereover an upper eye 53 formed upon the upper end of theconnecting element or wire 43. Thislatchlever 44 is provided with aninner horizontal arm 54 adapted to support the counter-weight 55, andalso has a depending verticalarm56 having a supporting shoulder 57 onits lower end facing outwardlyto receive thereagainst the inner edge ofthe valve controlling arm 32, as shown in dotted lines in Fig. 1, and invsection in Fig. 3.

The counterbalancing weight is adjustable so as to vary the eil'ectiveVweight of theoat 41 when surrounded by thefluid The counter-weight 55may be of any desired shape, form or size, but for the purposes ofillustration,is shown in thepresent instance, as comprising alat'relatively thin disk pivoted at its centraliportion upon the topflat `Jface of the horizontal arm 54 of the latch lever by means of anadjustable screw 58 beneath which is placed a. spring washer 59, theends of which are oiset romone another out of the planeofithe washer toyieldingly holdthe disk against the arm 54. Oneedge ofthedisklisprovided withthe fbody of :the weight, .the same 'being in the form of asubstantially semi-circular block or thickened `flange upstanding ,fromthe disk, and being of sulicient size to counterbalance the vfloat 41 tothe desired extent. The outer edge of the ldisk andthe outer Aface vofthe body `portion of the weight 55 indotted lines the innermost positionof the weight 55, showing that the weightis disposed substantially inthe vertical plane of the pivot 51 of `the latch lever, so that `thee'ective `weight of the horizontal arm 54`is practically eliminated.

The depending vertical arm 56 of the latch lever carries Vtherein ananti-friction roller 60, which projects slightly above thc supportingshoulder 57, and is adapted for direct contact'with the opposite facesand `the inner edge offthe valve arm 32. It will be noted that the lowerouter side of this arm 56isbeveled.inwardly and downwariilly so as toexpose a substantial portion ot the periphery of the-roller 60 and tobring the. roller 60 into conta ct with the arm 82, when the latter isswung up to open the valve 17. VVhenthe device is set in the openposition,v the parts assume the positions shown in Fig. 3 oflthedrawings. In this arrangement cit the parts, the lloat 41 `holds thelatch lever down inlocked positionto secure 'the roller 57`beneath thearm 32 and hold itin raised position against the tensionof Vthe spring18. As soon as the float 41 is raised a suililcient distance, the weight55 advances the lever 44 during `the upward movement of the float'itotake up any slack therebetween, and swings the supportingarm 56 inwardlya suili'cientdistance to admitthe release ot the `valve arm 32 from theshoulder 57. Then this condition arises, the arm 82, under the action ofthe spring 18, presses the roller 57 down to retract the latch lever,the anti-friction roller admitting of the easy operation of the partsand oitsctting undue Wear betweenthe shoulder 57 and the inner edge ofthe arm 32. Thus, as the friction is reduced, the action of the latchlever a quick one, so that the arm 32 is quickly re leased and the valve17 immediately closed uponthe raising of the float to the predeterminedheight. The counter-weight 55 may be adjusted into various positions toregulate the desired counter-action uponthe float 43to increase ordecreasethe effective weight of the latter, so as to admit of the lineadjustment of this improved barrel filler, irrespective oi" the specificgravity, or

4other characteristics of the liquids, which are passed throughthe'device.

As shown in Fig. 2 of the drawings, the nozzle 37 is preferably providedwith au adjustable support 61 in the form of a split sleeve havingoutstanding ears 62 at one side through which is passed a clamping bolt63 for contracting the ears and binding the sleeve 61 on the nozzle.Depending legs 64 radiate from the sleeve 61 and are adapted to restupon the head 65 of a barrel 66. The legs 64 are spaced about the nozzleto admit the insertion of the nozzle downwardly through a bung, or anopening 67, in the head 65 ofthe barrel, and to support the nozzle atthe desired height through the opening 67.

From the above description, taken in connection with the drawings, it isbelieved that the operation of the device will be clearly understood,for, when the parts are in set position as shown in Fig. 3, and indotted lines in Fig. 1, the valve 17 is open so that the fluid ispermitted to pass freely from the inlet nipple22, through the body15,-and outwardly through the lower crescent shaped end of the nozzle37. The tubel 45 prevents the liquid from entering the float chamber atthe top thereof, the lateral :disposition of the'openings 40 in the sideof the float chamber prevents the suction of thev outflowing liquid fromeffecting the con tents of the lioat chamber. The roller 60 supports thearm 32 in horizontal position at the forward end of the guide 33 to holdthe linger 25 up against the abutment 24, and supports the valve 17above the seat against the tension of the spring 18. As soon as'thefloat 41 is raised sutliciently to relieve the outer end of thelatch lever 44 of the weight of the float, the weight 55 swings thelatch lever 44 upwardly at its outer end and moves the shoulder 57 frombeneath the arm 32. The arm 32 now forces the roller 60 inwardly frombeneath the arm, the roller reducing frictional contact between the arms56 and-32, and admitting ofthe quick action of the arm 32 in swingingdownwardly and backwardly to seat the valve 17. Should it be foundnecessary to adjust the counter-weight 55, the same may be turned byhand about its pivotal support 58, so as to dispose the center ofgravity of the weight 55 at the desired distance from the pivot pin 51of the latch lever.

When it is desired to gain access to the interior of the device, or topack the same for shipment, or for any other reason to se arate thenozzle from the body 15, it is on y necessary to turn thenozzle upon thebody .to unscrew the nozzle therefrom, the

float connection with the latch lever being concentric to the nozzle andthe body 10, so that the parts will not be dislodged, and will nothaveto be removed prior to the turning of the nozzle. When the nozzle isunscrewed, it is only necessary to draw the same downwardly, so as toremove the socket from about the lower end of the tube 45, and withdrawthe connecting element 43 from the lower end of the tube to entirelydisconnect the Vnozzle from the body. It is, of course, understood thatprior to the turning Vof the nozzle, the connecting wire 43 must bedisengaged from the hooked end 52 of the latch lever.

In the present practical embodiment of the invention, from which theaccompanying drawings have been made, the latch lever or pawl 44 isprovided with spacing bosses 68 at its opposite sides and through whichthe pivot pin 51 passes. lThe bosses take up the frictional contactbetween the lever 4-4 and lthe ears 49 and 50, and serve to steady thelever in its swinging movements.

It is, of course, understood that various changes and modifications maybe made in the above specifically described construction, withoutdeparting fromthe spirit of this invention and being restricted only bythe scope of the following claims. I I
